Even for flat implicit linear systems (i. e. having more state components than state equations), reachability is a well defined concept in terms of the set of state trajectories: it characterizes the property that from any initial state can start a smooth state trajectory which reaches any final state. What can happen, however, for this general class of systems, is that a system with no control...

in this paper an optimal controller is proposed for a self-balancing electrical vehicle called segway pt. this vehicle has one platform and two wheels on the sides and the rider stands on the platform. a handlebar, as a navigator, is attached to the body of segway, with which the rider controls the vehicle. since segway uses electrical energy produced by batteries, resource consumption manageme...

The article considers the problem of finding optimal on average control trajectories continuous stochastic systems with incomplete feedback. This class problems includes in which initial states are described by a given distribution law; random effects object taken into account; and it is also assumed that information available only about some coordinates state vector. As special cases, determin...

A new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. We use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. Then, we linearized this identified model at each sampling time to have an approximate linear time varying system. In order to stabilize...

in this paper, a novel patch geodesic derivative pattern (pgdp) describing the texture map of a face through its shape data is proposed. geodesic adjusted textures are encoded into derivative patterns for similarity measurement between two 3d images with different pose and expression variations. an extensive experimental investigation is conducted using the publicly available bosphorus and bu-3...

This study presents LPV H∞ control with an augmented nonlinear observer (ANOB) to improve both the position and yaw tracking errors for Sawyer motors. The proposed method consists of forces torque modulation scheme, ANOB, a Lyapunov-based current controller state feedback guarantee stability error dynamics. ANOB is designed estimate all variables including position, velocity, current, disturban...
